Description

Technical Field

[0001] The present invention relates to a safety hanging rod for a single-column voltage transformer, which is applied in the technical field of maintenance equipment for primary substation equipment. Background Art

[0002] As is well known, during the routine inspection of single-column equipment such as current voltage transformers and lightning arresters, operators often use the method of jointly erecting a scaffolding by multiple people to provide a hanging point for the safety belt for maintenance personnel. During the operation processes such as the routine inspection of line voltage transformers and the routine inspection of main transformers in daily substation maintenance work, there is no safety belt hanging point that meets the requirements and "hangs high and uses low". Therefore, it is necessary to find a reliable fixed point on-site to install the base. However, in actual operation, due to site conditions, it is very troublesome and time-consuming to find the fixed point, resulting in low work efficiency. Moreover, currently, the joints of the existing bases and safety hanging rods use iron clamps with bolts for fastening, which takes a long installation time and requires many accessories that are easily omitted and lost. Therefore, we urgently need to develop a set of safety hanging rod devices suitable for the flanges of various types of primary equipment in substations. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides a safety hanging rod for a single-column voltage transformer, which is universal for the flanges of various primary substation equipment, easy to carry and quickly and reliably installed, effectively improving the maintenance efficiency while providing a safety hanging point for maintenance personnel.

[0004] The technical solution of the present invention is as follows:

[0005] A safety hanging rod for a single-column voltage transformer includes a first hanging rod and a second hanging rod. The first hanging rod and the second hanging rod are fixed through a connecting piece. A hanging ring buckle is provided on the second hanging rod. The bottom of the first hanging rod is fixedly connected with a sleeve. The front end of the sleeve is fixedly connected with a first clamping portion. The two sides of the first clamping portion are respectively hinged to a second clamping portion and a third clamping portion. Locking screws are rotatably arranged on the first clamping portion, the second clamping portion and the third clamping portion.

[0006] Both the first hanging rod and the second hanging rod are of a cylindrical structure. Pin holes are provided at the top and bottom of the first hanging rod and the second hanging rod. The second hanging rod is connected to the hanging ring buckle through the pin hole at its top. The end of the hanging ring buckle is fixed by setting a spring washer, a flat washer and a locknut. The bottom of the second hanging rod and the top of the first hanging rod are respectively inserted into the connecting piece.

[0007] The connecting member includes an upper connecting rod and a lower connecting rod. Both the upper connecting rod and the lower connecting rod are cylindrical structures. An annular limit is non-removably arranged between the upper connecting rod and the lower connecting rod. The diameter of the annular limit is greater than that of the upper connecting rod and the lower connecting rod. Pin holes adapted to the second hanging rod and the first hanging rod are respectively formed in the side walls of the upper connecting rod and the lower connecting rod. The upper connecting rod and the lower connecting rod are respectively sleeved on the bottom of the second hanging rod and the top of the first hanging rod. The upper connecting rod and the lower connecting rod are respectively fixed to the second hanging rod and the first hanging rod by arranging fixing pins in the pin holes. The bottom of the first hanging rod is inserted into the sleeve.

[0008] The sleeve is a cylindrical hollow structure with an open top. A pin hole adapted to the first hanging rod is formed in the side wall of the sleeve. The sleeve is inserted into the bottom of the first hanging rod and connected by arranging a connecting pin in the pin hole. A locking R pin is arranged at the end of the connecting pin for fixing. A fixing plate is non-removably connected to the front side of the sleeve. The front side of the fixing plate is detachably connected to the first clamping part by arranging a precision reamed hole bolt. The two sides of the first clamping part are respectively hinged to the second clamping part and the third clamping part by connecting bolts.

[0009] The first clamping part, the second clamping part and the third clamping part are all "U"-shaped structures with openings facing forward. The back plate of the first clamping part is fixedly connected to the fixing plate. Cylindrical clamping blocks are non-removably arranged on both sides of the first clamping part. Through holes penetrating through the top and bottom thereof are formed in the clamping blocks.

[0010] Slots adapted to the clamping blocks are respectively formed on both sides of the second clamping part and the third clamping part. Through holes penetrating through the top and bottom of the second clamping part and the third clamping part are formed in the slots. Connecting bolts are used to pass through the through holes to connect the second clamping part and the third clamping part to the first clamping part respectively. Spring washers, plain washers and lock nuts are arranged at the bottom of the connecting bolts.

[0011] Jack holes for passing through the locking screw are respectively formed on the front sides of the top surfaces of the first clamping part, the second clamping part and the third clamping part. Threads are arranged in the jack holes to rotatably connect with the locking screw. A connecting ring is arranged at the bottom of the locking screw. A rubber pressing block is fixed to the bottom of the connecting ring.

[0012] The present invention has the following beneficial effects:

[0013] 1. When the present invention is in use, direct insertion connections are adopted between the second hanging rod, the first hanging rod and the sleeve. There will be no loosening phenomenon after the sleeve is fixed to the first clamping part, the first clamping part is fixed to the second clamping part and the third clamping part. The disassembly and assembly are convenient, time-saving and labor-saving. The time from the start of installation to the reliable provision of the seat belt hanging point is less than or equal to 5 minutes, which can improve the maintenance work efficiency, shorten the time for providing a reliable seat belt hanging point for maintenance personnel, and save labor costs.

[0014] 2. The first clamping part, the second clamping part and the third clamping part provided by the present invention are used in cooperation, so that during use, the second clamping part and the third clamping part can swing on both sides of the first clamping part with the connecting bolt as the center of the circle, and then adjust the angle according to the objects with different shapes on site for clamping. The locking screw can adjust the pressing force according to the specific height of the clamped object, and a rubber pressing block is arranged at the bottom of the locking screw. Rubber has the function of buffering and shock absorption, making the force on the rubber pressing block more stable and reliable.

[0015] 3. The hanging ring buckle provided by the present invention provides a reliable seat belt hanging point for maintenance personnel. Once an operator falls, it can firmly hang the fallen person in the air without damaging the equipment and the device itself, effectively preventing the person from falling directly from a height to the ground and causing major personal injury accidents. The safety reliability reaches 100%, ensuring the personal safety of maintenance personnel. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The working principle of the present invention:

[0029] When using the present invention, first, connect the first hanging rod 5 and the second hanging rod 7 through the connecting piece 6. Insert the top of the upper connecting rod 61 into the bottom of the second hanging rod 7, and insert the bottom of the lower connecting rod 63 into the top of the first hanging rod 5, so that the limiting ring 62 is clamped between the first hanging rod 5 and the second hanging rod 7. Then, by rotating the first hanging rod 5 and the second hanging rod 7, the pin hole 64 at the bottom of the second hanging rod 7 is communicated with the pin hole 64 on the upper connecting rod 61, and the pin hole 64 at the top of the first hanging rod 5 is communicated with the pin hole 64 on the lower connecting rod 63. Further, fix the first hanging rod 5, the connecting piece 6 and the second hanging rod 7 by inserting the fixing pin 12 into the pin hole 64. Then, pass the hanging ring buckle 8 through the pin hole 64 at the top of the second hanging rod 7 and fix it at the end of the hanging ring buckle 8 through the spring washer 9, the plain washer 11 and the locknut 10. Further, insert the bottom of the first hanging rod 5 into the sleeve 4, so that the pin hole 64 at the bottom of the first hanging rod 5 is communicated with the pin hole 64 on the sleeve 4. Then, insert the connecting pin 13 into the pin hole 64 and use the locking R pin 14 to fix the first hanging rod 5 and the sleeve 4. Next, insert the precision reamed bolt 15 into the back plate of the first clamping part 1 and the fixing plate 23 to fix the first clamping part 1 on the sleeve 4. Then, align the clamping grooves 18 on the sides of the second clamping part 2 and the third clamping part 3 with the clamping blocks 16 on both sides of the first clamping part 1 respectively, and insert the connecting bolts 19 from the tops of the second clamping part 2 and the third clamping part 3 respectively to connect the clamping grooves 18 and the clamping blocks 16 together.
